What number should the hotel book?

Generally speaking, the check-in time of a hotel is noon 12 (star hotel) and the check-out time is the next day 12, which can be extended to 14.

In your case, if the hotel is reasonable, it should be regarded as the cost of one day without calculating the cost before you 12 check in.

The scheduled departure time is naturally written on the 26th.

Hope to adopt!
